Sorry I took a while, but here: App Button Remove the RSS reader in the top-right is Digest The rest is just moving stuff around/removing stuff with the built-in customization reachable by right-clicking blank space at the top. An even more vertical-space saving configuration I use is putting the URL bar up with the tabs - in that case I remove the extra stuff from it like that star with another extension I forget the name of, but it's easy to find.
